SMDA05C-7 THRU SMDA24C-7 Bidirectional TVS Array for Protection of Seven Lines PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The SMDAxxC-7 series of transient voltage suppres- Transient protection for data lines to sors are designed to protect components which are IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) connected to data and transmission lines from voltage IEC 61000-4-4 (EFT) 40A (5/50ns) surges caused by electrostatic discharge (ESD), electri- IEC 61000-4-5 (Lightning) 12A (8/20s) cal fast transients (EFT), and lightning. Small SO-8 surface mount package Protects seven I/O lines Working voltages: 5V, 12V, 15V and 24V TVS diodes are characterized by their high surge Low leakage current capability, low operating and clamping voltages, and Low operating and clamping voltages fast response time. This makes them ideal for use as board level protection of sensitive semiconductor Solid-state silicon avalanche technology components. The SMDAxxC-7 is designed to provide Mechanical Characteristics transient suppression on multiple data lines and I/O ports. The low profile SO-8 design allows the user to JEDEC SO-8 package protect up to seven data and I/O lines with one pack- Molding compound flammability rating: UL 94V-0 age. Marking : Part number, date code, logo Packaging : Tube or Tape and Reel per EIA 481 The SMDAxxC-7 TVS diode array will meet the surge Applications requirements of IEC 61000-4-2 (Formerly IEC 801-2), Level 4, Human Body Model for air and contact RS-232 and RS-422 Data Lines discharge.
